Composite Layers “MgAl Intermetalic Layer / PVD Coating” Obtained On The AZ91D Magnesium Alloy By Different Hybrid Surface Treatment Methods

Abstract: Magnesium alloys have very interesting physical properties which make them 'materials of the future' for tools and machine components in many industry areas. However, very low corrosion and tribological resistance of magnesium alloys hampers the implementation of this material in the industry. One of the methods to improve the properties of magnesium alloys is the application of the solutions of surface engineering like hybrid technologies. In this paper, the authors compare the tribological and corrosion prop… Show more

“…[123] The application of nitride layer along with coating layer deposited by PVD and CVD processes helped in protection of forging tools from plastic deformation. [12,26,34,[124][125][126][127] 4) The durability of forging tools can be significantly enhanced by variation of forging process parameters, optimization of forging tool design, surface treatment of forging tools, application of lubrications during forging process, and appropriate selection of forging tool material. [4,12,28,30,131,138,151,152] 5) The continuous monitoring of forging tool life, quality of forgings, effectiveness of forging machine, forging process parameters, and improvement in acquisition of forged image is important for good performance of forging process.…”

“…The hybrid layer with coating of TiCrAlN was highly effective for hot forging process, while TiBN coating was effective for semi-hot forging tools. [12,26,34,[124][125][126][127] Behrens et al [128] studied the effect of incorporating Si 3 N 4 segments using brazing and coating of TiB 2 on hot forging die steel. On comparing wear exhibited by conventional steel, Si 3 N 4 had shown a significant reduction in wear.…”

“…Multi-step processes, which overcome the aforementioned limitation by separating the diffusion step from the coating step, have been demonstrated to successfully fabricate continuous intermetallic compound coatings on Mg alloys [33][34][35][36][37][38][39]. Most of the previous works have been carried out by prefabricating a continuous Al layer on the Mg substrate.…”
